Constitution Checks

Constitution checks are uncommon, and no skills apply to Constitution checks , because the endurance this ability represents is largely passive rather than involving a specific effort on the part of a character or monster. A Constitution check can model your attempt to push beyond normal limits, however.

The GM might call for a Constitution check when you try to accomplish tasks like the following:

• Hold your breath
• March or labor for hours without rest
• Go without sleep
• Survive without food or water
• Quaff an entire stein of ale in one go

Hit Points

Your Constitution modifier contributes to your Hit points . Typically, you add your Constitution modifier to each Hit Die you roll for your Hit points .

If your Constitution modifier changes, your Hit point maximum changes as well, as though you had the new Modifier from 1st level . For example, if you raise your Constitution score when you reach 4th level and your Constitution modifier increases from +1 to +2, you adjust your Hit point maximum as though the modifier had always been +2. So you add 3 hit points for your first three levels , and then Roll your Hit points for 4th level using your new Modifier . Or if you’re 7th level and some effect lowers your Constitution score so as to reduce your Constitution modifier by 1, your Hit point maximum is reduced by 7.
